I'm trying to create a private, anonymous poll, that is only accessible to logged in users. I'm having trouble with a couple things.

1) When the poll is set to private, I get the error "You are not authorised to view this resource." on the frontend, when I try to vote.

2) If I disbale private poll and cast a vote, I'm able to refresh the page and cast additional votes. How do I prevent the user from doing this? They should only be allowed to vote once.

Regards,

Steve
